About The Debate Of The Philosophical Foundation For QFT

The paper initiates the history of conceptual foundation for QFT. From preconceptions, such as particles and fields, to post-introducing conception set, it reveals the program of conception revolution, pointing out the divergence difficulty. It lead to repel reductionism in classical physics and revive the antireductionism. Finally, I note that scientific theory always emerges from special context, both reductionism and anti-reductionism are partial ones, so that the real problem is rebuilding a brand new philosophical foundation-contextualism.To access to this purpose : firstly, I review how the "particle-wave duality" developed to "particle-field duality" .Then I clear out the post-conception difficulty in the mathematic system building process. At last ,1 note that particle & field co-exist ontology embarrassment. Accordingly, we can look through the mathematical window to find some information about the reality. Essentially, conceptual & mathematic difficulties arise from the philosophical foundation, but QFT is just a phenomenal theory , and it is essentially only a empirical contextual result.The innovation of the paper is it bet conceptual set include two parts—preconception & post-conception induced in math system. Point out renormalization processing is the initiator to the war between antireductionism & reductionism .All in all, the prevailing methodology is contextual one.The difficulties for the paper are : 1 .The physics frontier-QFT is hard to master. 2. Clarification for the confusing philosophy foundation is a complex work. 3. From what philosophical point to conjoin is a challenge.
